Application filed October 22, 1919. Serial No. 332,413.

To all whom t may concern.'

Be it known that I, KARL M. HAMILTON, a citizen of the United States, residing in Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Car End Frames, of which the following is a specification.

The invention relates to refrigerator cars and principally to a fraliie construction for the ice compartment, said frame being stronglyV united and made unitary with the end frame of the car and with the partition which separates the ice compartment from the freight compartment of the car.

An object and result of the improvement are that the body of ice is properly supported and confined and the racking of the car frame sheathing and partition is prevented, so that the durability of the frame and car body generally is greatly increased.

Writh such object in view, as well as other advantages which may be incident to the use of the improvements, the invention consists in the parts and combinations thereof hereinafter set forth and claimed, with the understanding that the several necessary elements constituting the same may be varied in proportions and arrangement without departing from the nature and scope of the invention.

In order to make the invention more clearly understood there are shown in the accompanying drawings means for carrying the same into practical effect, without limiting the improvements, in their useful applications, to the particular constructions which, for the purpose of explanation, have been made the subj ect of illustration.` In the said drawings Y Figure 1 is a vertical longitudinal section of the end portion of a car body, showing portions of the frame and taken through the ice compartment on line 1 1 of Fig. 2.

Fig. 2 is a. plan view of the sameY with the top sheathing and some of the frame members removed. 'l

Fig. 3 is a vertical transverse section of the roof portion of the car on line 3 3e of Fig. 2," but showing slight modifications of the car structure.

Fig. 4 is a vertical transverse section of the eaves Fig. 2.

Fig. 5 is a vertical longitudlnal section of portion of the car on line 4 4 of an upper end of Fig. 2.

Fig. 6 is a vertical longitudinal section of an upper portion ofthe lcar on line 6 6 of Fig. 2.

Referring to the drawings, the car frame as illustrated comprises center sills 1, end sills 2, side sills (not shown), side plates 3 ofthe roof frame, end plates 4, carlines 5, side sheathing 6, end sheathing 7, top sheathing 8, side fascia 9. and end fascia 10. These parts are or may be of usual or suitable construction. The floor 11 is supported by the; bottom frame members and is formed with air spaces 12 which are non-conductive of heat.

The ice and freight compartments are indicated generally by the numerals 13 and 14, the latter extending to the other end of the car (not shown), or to the other ice compartment in case the car be provided with one of the same at each end. These ,compartments are partly separated by a partition 15 having upper and lower air circulation openings 16 and 17.

The frame of the ice compartment is or may be constructed as follows: 18, 19 indicate horizontal transverse frame members extending across the car at the top of the ice compartment, the member 18 being secured to the endl plate 4 by bolts 20, and the member 19 being at the inner side of the ice compartment substantially over the partition 15 and attached and supported independently of the car side frame.

21 indicates longitudinal frame members arranged one at each side of the median line portion of the car on line 5 5 of the car and bolted or riveted at their ends at 22 to said transverse members 18 and 19. The frame further comprises longitudinal lside members 23 which are arranged inside of the side frame and sheathing of the car and independent thereof and are bolted or riveted to said transverse members at 24. The above described frame members are of convenient structural shape, bars of L-shape being illustrated. 25 indicates a horizontal reinforcing bracket plate having its ends arranged at the intersection of the bars 21 with thebar 18 and to extend from one to the other and connecting said intersections, this bracket plate being riveted to the bars 21 at 26 and to the bar 18 at 27, and it is also preferably perforated to receive the l rivets 22. 28 indicates corner bracket plates arranged at the intersections ot the lbars 23 With the bar 18 and riveted to the Jformer at 29 and to the latterf at 30, being also preferably perforated to receive theV rivets 24. 31 indicates horizontal bracket plates arranged at the intersection of the'bars 23 With the bar 19. and riveted to the former at 32 and to the latter at 33, being also preterably perforated to receive the rivets 24. 34 indicates horizontal bracket plates, shown rin dotted lines in Fig. 2, arranged at the intersection of the bars 21 with the bar 19 and riveted to the 'former at 35 and tothe latter atl 36, being alsopreterably perforated to receive the rivets 22.

The bars 23 are extended for a considerable distance inward from the transverse bar 19 and their ends are strongly connected and braced with the middle portion of the said frame by horizontal Ydiagonal bars 37 which are riveted at 38 to the bars 23 and v are strongly united thereto.

trated by the bolts 41 (Fig. 1) which pass through them and through the Vend plate 4.v

Certain of said bolts 41 also pass through the transverse bar 18 and make' the same rigid with the end plate andV With the end trame of the car generally.

lVhilethe braced trame above described doesnot derive its strength and lateral stitiness from the side frame elements of the car, it mayV be connected therewith as by bolts 42"(Figs. 1 and 4) Which pass throughy the' side bars 23 and through the side trame members of thecar body.

The said trame is supported from below by suitable vertical posts 43 rising from the bottom trame ot the car body, andto said posts are attached horizontal cross bars 44 and to the latter vertical slats 45 to form a V grating to keep the cakes of ice in position. The ice is supported upon a bottom grid 46 at a suitable distance above the floor oi the car. 47 Y is an opening into the car roof leading into the compartment 13 through Which ice may be charged' into the latter, (Fig.

The vertical boards forming the opening 47 or may be supported by the elements '21 and 23 as seen in Fig. 3, and also by the i frame elements 18 and 19 it desired.v

The upperpart ofv'zthe. car body is preterably cut off 'as an air chamber by `a subsheathing 48. An inner side sheathing 49 forms non-conducting airV spaces 50 in the sides ot the car. The top of thel compartment 13`is provided with a suitable sheathing 51, which may be double as shown in Fig. 5, forming an additional non-conducting air space 52; and the end Wall oi the 70 compartment 13 is formed by a suitable inner end sheathing 53.

The trame comprising the elements 18, 19 etc., is in itself stiff andV rigid in horizontal planes. When it is attached to side members ot the car frame it renders stiit and holds from distortion theV car body.
